Use latest LSP4J release (cuts off some dependencies)

[mickaelistria]

JDT-LS seems to still depend on older LSP4J, which requires xbase and other dependencies. The latest release removes needs for some dependencies. This would make it noticeably simpler to set up some non-standard dev environments mixing various projects.

Do you know which dependencies? We use xbase in our code for custom protocol classes, and pretty much only to annotate with @Pure.

I don't see any reductions in dependencies going from LSP4J 0.22.0 to 0.23.1.

I think the main one I had in mind was xbase. Also, IIRC moving to latest LSP4J allows to get rid of 1 older version of guava.

It updated guava and gson but the duplicate version of guava I think was fixed a while ago in a previous lsp4j.
